To all whom it may concern:

Be it known that 1, Josh GAPDEVILA, a subject of the King of S ain,residing in New York city, county of ew York, and State of New York, andwhose post-oilice address is No 119 West Forty-third street, New Yorkcity, have invented certain new and useful Improvements in Re air-Heelsfor Rubber Footwear; and. I do hereby declare the following to be afull, clear, and exact description of the invention,such as will enableothers skilled in the art to which it appertains to make and use thesame.

My present invention relates to a repair heel for rubber shoes, bootsand the like and is especially directed to a heel designed to meet theparticular requirements ofshoe repairers who do not ossess app-1 ratuswith which to carry out vu canizing operations.

The inventlon contemplates a repair heel which is applicable to rubberfootwear which has undergone various degrees of wear, by cementing aloneand without eniploying vulcanization. Where a repairheel has beenapplied to a worn rubber shoe or the like by means of rubber cement orother adhesive, it has been dlll'lclllt to make such 'an attachment ofthe repair heel as will withstand the wear and tear of use withoutbecoming detached. The deforming characto avoid as far as possible theapplication of the strains due to deformation of the rubber when stoodupon to the points of attachment of the repair heel tothe rubber shoe, Ihave incorporated fabric with the rubber of the repair heel whichprevents in a great Incasure the deformation of the heel, and thereforeavoids the conduction of the strains from one part to another, and lhave preferably incorporated the fabric as aiming in which position itplays another important part in providing a suitable suriace tor theadhesive cement, as I have discovered by long observation that it isimpracticable to firnilyattach two rubber surfaces by the ai of cementwithout the employment of a vulcanizing I operation.

In furtherance of the attainment of the objects in view. I have made theupper parts of the walls of my repair heel thin and have refrained fromextending any reinforcements upwardly upon these walls to anyconsiderable extent in order to avoid im-' parting such distortions ofthe lower part of the heel as invariably accompany the placing of theweight upon the heel, to the points of attachment of the walls of theheel adjacent the upper edges of the surrounding walls. I haveinclinedthe forward 'wall of the heel outwardly and extended this wall toconstitute an attachment flap of considerable length that it may becemented to the arch of the sole of the rubber shoe where it is notsubjected. to wear and where it may present a large surface for firmattachment to resist the dragging action which is prescut when the heelstrikes the ground with a forward motion.

As the heel 01"? a rubber shoe wears quickly near its rear edge and as agreater or less amount of material may be missing from the repair heelis attached in order that the I repair heel may not crush and cause adetachment of its walls from the shoe. 1 have provided wedges ofsuitable material by the use of one or moreoi which the repair heel maybe built up from within to avoid the occurrence of this space andpreferably provide one side of each of these wedges with fabricto afforda suitable surface for cementing thev wedges together, to the innersurface of the repair heel and to the surface of the shoe to which theheel is to be attached. l: prefer to make a partial attachment of asuilicient number of these wedges in their proper position within therepair heel to accommodate for the maximum per- "mis'sible amount ofwear of the heel of the shoe to be repaired. this partial attachment thewedges are associated with the heel in a manner to prevent their lossprior to use and in such a way that the top one or more or all be easilydetached by the repairer. leaving that or those required to. compensatefor the wear upon the shoe to be reheeled. it is then only necessary forthe repairer to cement the remainin wedges to the interior of the heeland together and cement the heel to the shoe.

l. have illustrated in the accompanying drawing an embodiment of myinvention,

Referring to, the drawing, the repair heel shown comprises a bottomupstanding outwardly inclined walls 6, the rear well being preferablyprovided with a reinforcement 0 connecting with the tread a whichreinforcement 0, how ever, should'notextend to the upper edge of therear wall biit terminate at such a height upon that wall as will leave athin attacharound the .upper edge of this rear wall, the height of whichattachment portion should be a considerable part of the heightof therear wall, preferably about half. The forward outwardly inclined wall 6is extended to form a thin-flap e which is to be cemented to the undersurall way make the tight'attachment of the heel.

with cement and by slight attachment at one face of the arch of the shoeto which the heel is to be attached.

preferably molded of rubber or rubber composition. The entire innersurface of thg heel and the flap e is lined with fabric f to whichnement securely adheres. The upper portions of the walls I) The heel isare niade thin in order that they may be easily accommodated to thesurface of the shoe, but as the fabric f prevents themfrom stretching,-strains are not concentrated at any'point to cause them to'tear orbecome detached .when firmly cemented to the shoe. ,When the flap 0 isfirmly cemented to the arch of the shoe it forms a continuation of theoutwardly inclined forward wall 5 and the pull upon the flap does nottend to distort the front wall as would be thecase if said wall werevertical or inwardly inclined, but is directly transmitted through saidwall to the-tread a. I prefer to provide easily deformable ridges g, g,on the interior of the edges of the side Walls 6 to enter and fill thedepression which occurs in arubb'er shoe where the vamp and sole meetand in this more easy of accomplishment. I provide the wedges h, e andto build up the interior of the heel at one side of the center of therear edge and I may make the lower wedge 7i integral-with the tread.and'locate it below the lining of fabric 1* or place it above thelining'andeecurely attaol it or make it detachable as is the case withwedges a and j, which are each provided with a fabric on one face andare preferably secured'in place edge permitting them to be eitherdetached by tearing out or firmly attached by being lifted up, coatedagain pressed down. l'Vhat I claim is I i 1.
